MICROWAVE MEASUREMENT
After adjustment of door latch switches, monitor
switch and door are completed individually or
collectively, the following leakage test must be
performed with a survey instrument and it must be
confirmed that the result meets the requirements
of the performance standard for microwave oven.
REQUIREMENT
The safety switch must prevent microwave
radiation emission in excess of 5mW/cm2 at any
point 5 cm or more from external surface of the
oven.
PREPARATION FOR TESTING:
Before beginning the actual test for leakage,
proceed as follows;
1. Make sure that the test instrument is operating
normally as specified in its instruction booklet.
Important:
Survey instruments that comply with the
requirement for instrumentations as prescribed
by the performance standard for microwave
ovens must be used for testing.
Recommended instruments are:
NARDA
8100
NARDA 8200
HOLADAY HI 1500
SIMPSON 380M
2. Place the oven tray into the oven cavity.
3. Place the load of 275 ± 15ml of water initially at
20 ± 5°C in the center of the oven tray. The
water container should be a low form of 600 ml
beaker with inside diameter of approx. 8.5cm
and made of an electrically non-conductive
material such as glass or plastic.
The placing of this standard load in the oven is
important not only to protect the oven, but also
to insure that any leakage is measured
accurately.
4. Close the door and turn the oven ON with the
timer set for several minutes. If the water begins
to boil before the survey is completed, replace it
with 275ml of cool water.
5. Move the probe slowly (not faster that
2.5cm/sec.) along the gap.
6. The microwave radiation emission should be
measured at any point of 5cm or more from the
external surface of the oven.
